摘要：为研究复合外加剂对高能球磨法制备铜金粉的影响,采用正交试验法,研究不同外加剂配方对高能球磨法制备的铜金粉的颗粒粒径、水面遮盖率的影响。结果表明:加入硬脂酸、棕榈酸和十二烷基苯磺酸钠的最佳质量分数分别为1.2%、0.3%、0.1%,制得的出料粉体粒径d₅₀=9.95μm,水面遮盖率为4 936.31 cm²/g。

Abstract： In order to research the effect of composite additives on preparation of bronze powder， the orthogonal test was carried out to investigate the effects of different additives formula on the fineness d₅₀ and water surface covering of bronze powder prepared with high energy milling. The result showed that the best mass fraction of stearic acid， palmitic acid and SDBS was 1.2% ，0.3% ，0.1% . The fineness d₅₀ and water surface covering was 9.95 μm，4 936.31 cm²/g respectively.
